Class direction for 'support-oriented' classes (BRD, MCH, AST)?

[Kemonologist]

In this game, the support who can bring DPS to party must trade their DPS or Healing potential for other member DPS.
e.g.
- MNK have highest raw DPS because they don't have any DPS support to party.
- DRG can increase party DPS from critical buff and piercing resistance debuff but this buff and debuff have limitation for increase DPS unlike NIN. Then, they get higher raw DPS more than NIN but lower than MNK.
- NIN have lowest raw DPS in melee because they can increase DPS for any job from Trick Attack and slashing resistance debuff that guarantee DPS increasing for 2 Tank. It is flexible more than DRG.
- BRD and MCH have buff for increase DPS to large member in party. When MCH can increase both physical and magical, they have short duration and potency lower than BRD who can increase only magical. TP and MP regeneration are indirect DPS increasing too (More resource, More damage). But their ranged attack and mobility make them must lower their DSP too. From that two reason, it make them have lowest DPS unlike NIN who have lose DPS from their flexible DPS utility only.
- Same with healer, WHM have best potential in healing because they don't have any party buff (except MND buff) when SCH and AST can bring DPS to party. SCH and AST must trade their raw healing potential with their DPS buff for party (SCH must trade their MND stat for pet too, They have lowest MND) when AST must trade their own DPS more than SCH because they have various buff effect more than SCH. However, they still get some unique mechanic in healing instead.
